We see something change in our climate and we blame ourselves ... I don't think we understand what happens. We can watch it happen on the (climate) models, we know it happens, but we don't know for sure how it happens.
Roy SpencerTemperature measurements in the arctic suggest that it was just as warm there in the 1930's...before most greenhouse gas emissions. Don't you ever wonder whether sea ice concentrations back then were low, too?
Roy SpencerI would wager that my job has helped save our economy from the economic ravages of out-of-control environmental extremism. I view my job a little like a legislator, supported by the taxpayer, to protect the interests of the taxpayer and to minimize the role of government.
Roy SpencerWe have no idea what's natural and what's man made. [...] There is no fingerprint of human-caused warming.
Roy SpencerIt is well known that strong to violent tornado activity in the US has decreased markedly since statistics began in the 1950s, which has also been a period of average warming. So, if anything, global warming causes FEWER tornado outbreaks...not more. In other words, more violent tornados would, if anything, be a sign of 'global cooling,' not 'global warming.'
Roy SpencerAl Gore likes to say that mankind puts 70 million tons of carbon dioxide into the atmosphere every day. What he probably doesn't know is that mother nature puts 24,000 times that amount of our main greenhouse gas-water vapor-into the atmosphere every day and removes about the same amount every day. While this does not 'prove' that global warming is not man-made, it shows that weather systems have by far the greatest control over the Earth's greenhouse effect, which is dominated by water vapor and clouds.
